Our process
-
Programming & siting – goals, adjacencies, utilities, truck flow, and site constraints.
-
Pre-engineered system selection – frame type, bay spacing, clear heights, crane/runway needs.
-
Foundations – geotech review, slab/pier design, vibration and thermal movement joints.
-
Envelope & performance – roof/wall panels, insulation strategy, daylighting, air/water barriers.
-
MEP & fire protection – HVAC zoning, electrical distribution, compressed air/gases, sprinklers per hazard.
-
Permitting & procurement – stamped drawings, energy compliance, long-lead management.
-
Erection & QA/QC – sequence planning, bolt tensioning, plumb/line checks, leak testing.
-
Close-out & handoff – O&M manuals, as-builts, warranties, training.
Specs & options
-
Structures: Rigid frame, clear-span, multi-span, lean-to, mezzanines, cranes.
-
Roof systems: Standing-seam cool roofs, high-temp underlayments, snow/ice detailing for high-country projects.
-
Walls: Insulated metal panels (IMP), ribbed panels, architectural accents, masonry/CMU hybrids.
-
Thermal & IAQ: Fiberglass systems, IMP cores, or spray foam; thermal breaks and vapor control to prevent condensation.
-
Openings: Sectional/roll-up doors, high-speed doors, canopies, louvers, and daylighting.
-
Site work: Paving, drainage, curb & gutter, equipment pads, exterior utilities.
Arizona considerations we design for
-
Monsoon resiliency: Uplift, lateral bracing, and high-capacity roof drains/scuppers.
-
Heat management: Cool-roof assemblies, shaded entries, and right-sized HVAC with economizers.
-
Energy code compliance: Envelope U-values, lighting power density, and commissioning documentation.
-
Dust & UV exposure: Coatings and sealants specified for high UV index and abrasive environments.
Timeline & cost drivers
Lead times and price are shaped by steel tonnage, clear height, crane loads, panel type, insulation R-values, site soils, utilities, and long-lead gear (electrical gear, RTUs, overhead doors). We provide early alternates to keep budgets predictable.
Maintenance & warranties
Post-turnover, we offer annual envelope inspections, roof fastener checks, sealant refreshes, and mechanical service to protect manufacturer warranties and avoid downtime.

FAQs
How long does a typical metal building project take?
Small shells can erect in 6–10 weeks after permitting; larger or crane-ready facilities often run 4–8 months end-to-end, depending on scope and lead times.
Are metal buildings energy efficient in Arizona’s heat?
Yes—cool roofs, continuous insulation, insulated metal panels, and well-zoned HVAC keep loads in check and help meet state energy codes.
Can you integrate offices and mezzanines inside the shell?
Absolutely. We regularly add conditioned office cores, mezzanines, labs, and restrooms with full MEP and egress compliance.
What foundations are typical on desert soils?
Most projects use slab-on-grade with thickened edges or piers/grade beams where soils require. We base designs on geotech reports to control settlement and vibration.
Do you handle permitting and inspections?
Yes. We prepare stamped drawings, coordinate plan review, and manage special inspections and close-out documentation.
